Lastimosamente este addon es compatible con versiones inferiores de FF3.6, por lo que aca les dejo una guía de como hacerlo funcionar en FF4:

1.  Download the Pencil-1.2-0-fx.xpi
2.  Unzip it with your favorite zip archiver
3.  Open install.rdf
4.  Locate the string - em:maxVersion="3.6.*"
5.  Replace it with - em:maxVersion="4.*"
6.  Save the file. Now your file should look something as shown in below screenshot

7.  Now archive all the files - install.rdf, update.rdf & chrome.manifest - and the directory - chrome - into one zip file and name it as Pencil-1.2-0-fx.xpi. It does not necessarily has to be Pencil-1.2-0-fx.xpi, you can have it as MyFile.zip or anything of your choice.
8.  Now open up Firefox 4, go to Tools menu and select Add-ons
9.  Click Install Add-on From File...
10. Select the archive you just created and you are done
